    摘要: Methods and apparatus for conditional access of non real-time (NRT) content in a distribution system. A method includes encrypting NRT content with a control word (CW) to generate encrypted NRT content, providing the CW to entitlement control message (ECM) generators, receiving ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and providing the encrypted NRT content and the ECMs for transmission over a distribution network. An apparatus includes a synchronizer configured to provide a CW to ECM generators and receive ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and a management module configured to encrypt the NRT content with the CW to generate encrypted NRT content and provide the encrypted NRT content and the ECMs for transmission over the distribution network.

    摘要: Embodiments enable mobile multimedia receiver devices to receive emergency alert messages from forward link only broadcast networks. Alert messages may be organized in alert sessions identified by an alert session ID. Alert record information may be included in the overhead information symbol (OIS) channel including the session ID and information enabling a receiver device to obtain an alert data message from an alert session in a multicast logic channel. The alert announcement may also be included in the service flow MLCs as an embedded OIS in a first superframe. The alert record may include the number of alert data packets the alert session so receiving devices can determine when they have received all data packets associated with a particular alert. By storing the alert session identifier in memory, receiving devices can ignore subsequent broadcasts of the same alert, thereby enabling them to conserve battery power.

    摘要: Methods and devices enable users of still or video image content to indicate objects within images in order to obtain more information regarding products of interest. Selected portions of an image or coordinates within the image may be included in a product query message transmitted to a server. The server receiving image information may process the information to recognize objects or particular products within the image selection. Recognized objects or products may be compared to a database of available merchandise to determine availability. Information regarding commercially available products may be included in a product information message transmitted to the user's computing device. Users may initiate a purchase transaction for recommended products based on the product information. The image may be broadcast by a variety of content delivery services including a mobile broadcast TV network.
